Ukusebenza kukaPfizer kwidosi yesiThathu yesitofu sokugonya se-COVID-19 'Kakhulu' esomeleza ukhuseleko

Umxholo

• Uphengululo lwe

Kwangoko kweli hlobo, kwakungathi ubhubhane we-COVID-19 ujikile kwikona. Abantu abagonywe ngokupheleleyo baxelelwa ngamaZiko oLawulo lweSifo kunye noThintelo ngoMeyi ukuba akusafuneki banxibe imaski kwiindawo ezininzi, kwaye inani lamatyala e-COVID-19 e-US nawo anqabile okwexeshana. Kodwa emva koko, i-Delta (B.1.617.2) eyahlukileyo ngenene yaqala ukukhulisa intloko yayo embi.

Umahluko weDelta unoxanduva malunga neepesenti ezingama-82 zeemeko ezintsha ze-COVID-19 e-US ukusukela nge-17 kaJulayi, ngokwedatha evela kwi-CDC. Ikwadityaniswe ne-85 yepesenti ephezulu yomngcipheko wokulaliswa esibhedlele kuneminye imicu, kwaye i-60 yepesenti yosulelo ngakumbi kunokwahluka kwe-Alpha (B.1.17), uhlobo oluphambili ngaphambili, ngokutsho kophononongo lukaJuni 2021. (Idibeneyo: Kutheni le nto i-Delta COVID eyahlukileyo isasazeka kangaka?)

Izifundo zamva nje ezivela eNgilani naseScotland zibonisa ukuba iyeza lokugonya lePfizer alisebenzi kangako ekukhuseleni ngokuchasene nokwahluka kweDelta njengoko kunjalo ngeAlfa, ngokweCDC. Ngoku, loo nto ayithethi ukuba isitofu sokugonya asikwazi ukukunceda ukuba uphephe isifo esineempawu ezisuka kuxinzelelo- oko kuthetha ukuba ayisebenzi kangako ekwenzeni oko xa kuthelekiswa namandla ayo okulwa ne-Alpha. Kodwa ezinye iindaba ezinokuba zimnandi: NgoLwesithathu, uPfizer ubhengeze ukuba idosi yesithathu yesitofu sokugonya se-COVID-19 inokonyusa ukhuseleko ngokuchasene nokwahluka kweDelta, ngaphaya koko kwiidosi zayo ezimbini zangoku.

Idatha ethunyelwe kwi-Intanethi isuka kwi-Pfizer iphakamisa ukuba idosi yesithathu yokugonya inokubonelela ngaphezulu kwamaxesha amahlanu amanqanaba e-antibody ngokuchasene nokwahluka kwe-Delta kubantu abaphakathi kwe-18 kunye ne-55 xa kuthelekiswa naleyo isuka kwimilinganiselo emibini. Kwaye, ngokufunyenwe yinkampani, i-booster yayisebenza ngakumbi kubantu abaneminyaka engama-65 ukuya kuma-85 ubudala, ikonyusa amanqanaba omzimba omzimba phantse ama-11 aphakathi kweli qela. Konke okuthethwayo, iseti yedatha ibincinci - ngabantu abangama-23 kuphela ababandakanyekayo- kwaye iziphumo azikaphononongwa ngoontanga okanye zipapashwe kwincwadi yezonyango okwangoku.

"Siyaqhubeka nokukholelwa ukuba kunokwenzeka ukuba idosi yesithathu inokuthi ifuneke kwiinyanga ezintandathu ukuya kwezili-12 emva kokugonywa ngokupheleleyo ukugcina awona manqanaba aphezulu okhuseleko, kwaye izifundo ziyaqhubeka ukuvavanya ukhuseleko kunye nokuqina komzimba kwidosi yesithathu," utshilo uMikael. Dolsten, MD, Ph.D., igosa eliyintloko lezenzululwazi kunye nomongameli we-Worldwide Research Research, Development, kunye ne-Medicalfor Pfizer, kwingxelo ngoLwesithathu. UDkt Dolsten uqhubekile wongeza, "Ezi nkcukacha zangaphambili zikhuthaza kakhulu njengoko i-Delta iqhubeka isasazeka."

Ngokucacileyo, ukhuselo olunikezwe sisiyobisi esisemthamo sesibini sokuthintela i-Pfizer singaqala "ukuncipha" kwiinyanga ezintandathu emva kokufakwa inaliti, ngokutsho kwengcaciso enkulu yezamayeza ngoLwesithathu. Ke, idosi yesithathu enokubakho inokuba luncedo ngakumbi, ngokulula, ekuxhaseni ukhuseleko lwabantu kwi-COVID-19 iyonke. Kubalulekile ukuba uqaphele, nangona kunjalo, ukuba amanqanaba e-antibody - nangona inkalo ebalulekileyo yokhuselo- ayisiyiyo kuphela i-metric yokulinganisa amandla omntu okulwa intsholongwane, ngokutsho. INew York Times. Ngamanye amagama, ixesha elininzi kunye nophando ziyafuneka ukuqonda ukuba ingaba ithamo lesithathu likaPfizer, liphosakele, konke kuqhekekile.

Ukongeza kwi-Pfizer, abanye abenzi beyeza lokugonya nabo baxhase umbono wokudutyulwa. Umseki weModerna uDerrick Rossi uxelele Iindaba ze-CTV ekuqaleni kukaJulayi ukuba isitofu sokugonya se-COVID-19 "kuya kufuneka ngokuqinisekileyo" ukugcina ukungakhuseleki kwintsholongwane. URossie wade waya kuthi, "Kungothusi ukuba sidinga i-booster shot ngonyaka." (Idibeneyo: Unokufuna i-Dose yesithathu ye-COVID-19 Vaccine)

UJohnson & Johnson CEO u-Alex Gorsky naye watsibela kwi-boosters-in-the-future train ngexesha Ijenali yeWall Street 's Inkomfa yezeMpilo kwezobuchwephesha ekuqaleni kukaJuni, esithi idosi (ii) eyongeziweyo inokufuneka kwisitofu senkampani yakhe - ubuncinci kude kube ngumhlambi wokuzikhusela (aka xa uninzi lwabemi lukhuselekile kwisifo esosulelayo). "Sinokuba sijonge oku kumakishwa kunye nomkhuhlane, mhlawumbi kule minyaka imbalwa izayo," wongeze watsho.

Kodwa ekuqaleni kukaJulayi, i-CDC kunye noLawulo lokuTya kunye neDrugs bakhupha ingxelo edibeneyo besithi "amaMerika agonywe ngokupheleleyo awafuni i-booster shot ngeli xesha" kwaye "i-FDA, i-CDC, kunye ne-NIH [amaZiko eSizwe ezeMpilo. ] babandakanyeka kwinkqubo esekwe kwisayensi, engqongqo yokuqwalasela ukuba ingaba i-booster iyimfuneko na.

"Siyaqhubeka nokuphonononga nayiphi na idatha entsha njengoko iya kubakho kwaye izakugcina uluntu lwazi," ifundeka ingxelo "Silungiselele iidosi zokunyusa ukuba kwaye xa inzululwazi ibonisa ukuba iyafuneka."

Ngapha koko, ngolwe-Lwesithathu uGqirha uDolsten uthe uPfizer "kwiingxoxo eziqhubekayo" neearhente zolawulo e-U.S malunga nenqanaba lesithathu lokuthintela iyeza lokugonya. Ukuba iarhente ithathe isigqibo sokuba iyimfuneko, iPfizer iceba ukungenisa isicelo sokugunyazisa ukusetyenziswa ngokungxamisekileyo ngo-Agasti, ngokukaGqirha Dolstein. Ngokusisiseko, unokufumana i-COVID-19 booster shot kunyaka olandelayo.

Ulwazi kweli bali luchanekile ngexesha lokushicilelwa. Njengoko uhlaziyo malunga ne-coronavirus ye-COVID-19 luqhubeka nokuvela, kunokwenzeka ukuba ezinye iinkcukacha kunye nezindululo kweli bali zitshintshile ukusukela ekupapashweni kwayo. Siyakukhuthaza ukuba ujonge rhoqo ngezixhobo ezinjenge-CDC, i-WHO, kunye nesebe lezempilo likarhulumente kwindawo yakho yokufumana olona lwazi lwanamhlanje kunye neengcebiso.
